In this paper, it analyzes and compares the use of three different materials
(Reinforced Concrete -R. C.-, Steel and Wood) usable for the building, and construction
processes that this entails. The analysis aimed to investigate which of the three materials
is the most appropriate from the perspective of sustainability in order to propose
alternatives that minimize the impact they have on the environment. Today, concrete is the
material most commonly used in construction, and therefore must be environmental
objective for reflection, that after analyzed, we can propose other typologies or alternative
materials. The analysis included projects single-family housing for each of the materials
and building systems proposed, these cases involved comparable properties within their
specific environments (rules and context Spanish) and process variables normalization
that validate the analysis. The work was developed using the software tool for managing, scheduling and forecasting of construction waste Net Waste Tool (NWT) Waste &
Resources Action Programmer, in which, it proceeded entering data, characteristics,
volumes, consumption and emissions of each entry or supplies described in the study
variables, and in this way, determine and quantify the pollutants vectors generated by
these. The analysis of the results obtained have been able to argue a selection of
materials for building sustainable new approach to waste generation, understanding that at
the end of a life cycle, process or matter that pollutes less is best
